This article ’ s purpose is to simulates the apron that adds the coarseness fluent speed of flow in to hang the upward distributed , through the comparison , absorbs other mathematical simulations in model and the method , established the surface two - dimensional current of water mathematical model of apron that adds the coarseness 本文以模擬海漫加糙后明渠紊流的流速在垂向上的分布規(guī)律為主要內(nèi)容,通過比較、借鑒其它數(shù)學(xué)模擬的建模方法,建立了海漫加糙后水流垂向二維數(shù)學(xué)模型。
